Application filed. February 17, 1922.

To all whom 412? mafz concern:

Be it known that l, RICHARD H. ll/lARTEN, a citizen of the United States, residing at Gainesville, in the county of Hall and State of Georgia, have invented a new and useful Wheel, of which the following is a specification.

This invention has reference to motor vehicle wheels, and more particularly to wire Wheel constructions.

The primary object of the invention is to provide a metal spoke wheel constructed in a manner to facilitate the application and removal of solid or pneumatic tires.

Another object of the invention is to provide a wheel havinga sectional rim, novel means being provided to move the rim sections towards the hub of the wheel to lessen the diameter of the rim.

A still further object of the invention is the provision of means for tensioning the spokes and locking the rim sections in their extended positions, eliminating any possibility of the rim sections contracting accidentally.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made withiri the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 is a side elevational View of a wheel constructed in accordance with the present invention.

Figure 2 is a sectional view taken on line 2--2 of Figure 1.

Figure 3 is a fragmental detail view of a wheel huh, a portion thereof being broken away to illustrate the connection between the hub and spokes.

Figure 4 is an enlarged detail view of the connection between the hub and spokes.

Figure 5 is a fragmented detail View of the felloe or rim disclosing the connection hetween the felloe and spoke.

Figure 6 is a bottom plan view of adjacent sections.

Figure 'I is a sectional view disclosing a demountable rim section positioned on a wheel constructed in accordance with the in- 'vention.

a hollow reduced portion 9 which accommodates the axle on which the wheel is mounted. This reduced portion 9 is formed with threads disposed throughout the length there of to accommodate the adjusting sleeve 10, which cooperates with the cap 11 to clamp the movable section or supporting ring 1523, to the reduced portion 9 of the hub. secured to the reduced section 9, and disposed hetween the cap 11 and supporting ring is a securing disk 13 which contacts with t o ring 12 to force the same longitudinally the reduced portion 9 of the hub, to tension the spokes, movement of the dish 13 being accomplished by rotation of the cap ill.

A groove 14: is formed in one edge the reduced portion 9 and accommodates the 15 carried by the supporting ring 12, so that rotation of the ring with respect to the huh or a wheel will be prevented.

Spaced ears are carried lay the inner sun face of the sections of the rim, the ears ing indicated at 16, and adapted to receive the reduced portions 17 of the spolres 18, which radiate from the hub. Shoulders 1'9 are formed at the outer ends of the respective spokes, which shoulders contact with the free ends of the ears to direct the strain. to the body portion of the spokesand at the same time relieve the pivot pins 20 which secure the spokes to the ears, of this strain.

The supporting ring 12 as well as the hoo each of the sections is formed with a tonggae 24:, which tongue has a shoulder to received within a suitable opening in the adjacent endofllhe cooperating section, suitable flanges 2d being formed on the sections and cooperating with the tonw gues to prevent lateral movement of the 5 tongues.

in the form of the invention as shown by Figure 7 of the drawing, the rim, which is indicated at 27 is formed with lugs 28 to be positioned in suitable openings fop med in 10 the rim 29, which carries the cushion tire 30.

From the foregoing it will be seen that due to the construction as described, a wire wheel may be readily and easily collapsed to reduce the diameter thereof, and allow the same to be readily andxeasily' positioned within a tire or rimbf a fixed diameter.

After the tire or rim has been positioned, the nut which is indicated at 31 and operates on the threaded portion 32 of the axle 33, is rotated to draw the body portion of the hub towards the supporting ring 12. The cap 11 is now rotated to force the disk 13 towards the supporting ring 12 to tension the spokes. If wear should occur between the elements of the wheel, the adjusting sleeve 10 may be readily rotatedto compensate for the wear, permitting the supporting ring 12 to be moved. into closer relation with the body portion 7 of the hub.

It might be further stated that the ears 21 are formed with a shank 3a which are positioned in suitable openings of the hub or rim section, the ends of the shanks being headed as at 35 to secure the ears in position.

Having thus described the invention, what is claimed as new is:

1. A wheel including a sectional rim, means for locking the adjacent ends of the sections together, spaced ears carried by the rim sections, an adjustable hub, ears carried 'by the adjustable hub, spokes pivotally sup hub, spokes for connecting the rim sections and hub, means for restricting movement of the supporting ring with respect to the hub, longitudinall thereof, and a cap positioned on one end 0 the hub.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
